Compare this shape with the Rhombic
Triacontahedron on the previous page. To form this polyhedron imagine
constructing a Dodecahedron around a Rhombic Triacontahedron is such
a way that each face of the Dodecahedron cuts five of the edges of
the Rhombic Triacontahedron in half, then discard any part of the
Rhombic Triacontahedron which lies outside of the Dodecahedron, and
voila!
